test: upgrade helm dependency for v4 beta

[jessesimpson36]

Which problem does the PR fix?

This PR is not intended for merge, as v4 is still in beta. But given how we are HEAVY users of helm, I think it's important to run the tests early on just to see what happens.

A new beta will be released on monday. I will then update .tool-versions and view the tests.
